Workers broke ground and started construction on the new Sam’s Club at Tikahtnu Commons in August. The Sam’s Club at Anchorage’s Penland Parkway location near the Northway Mall will move into the new 146,000-square-foot building upon completion of construction. The Sam’s Club on the Old Seward Highway in the Dimond area will remain open. The Sam’s Club at Tikahtnu Commons is expected to be completed and open in Aug. 2013.
